They actually deprecated it as many things were not working with a
separate /usr.  systemd has no more or less problems than anything else
that uses things on /usr.

I come from a Unix background -- separate /usr was deprecated in the
1990's with SVR4.2, I'm kind of amazed it took Linux so long to catch up.

In this particular case it's a bit irritating, it could be fixed by
moving liblz4 to /lib or by not linking the various lvm2 binaries
against libsystemd.

Presumably devuan and debian will have differing ideas of how and
whether this should be fixed.  :-)
